Phys.org / Unique fossil reveals the internal organs of a 245-million-year-old marine reptile
Scientists from China, Europe and the U.S., including Dr. Stephan Spiekman, a paleontologist at the State Museum of Natural History Stuttgart and the University of Hohenheim, have described a fossil of the long-necked marine ...
Phys.org / Scientists discover 210-million-year-old dinosaur in Zimbabwe
A newly discovered dinosaur from Zimbabwe is offering fresh clues to how the animals diversified, suggesting they spread across distinct ecosystems in southern Africa, scientists said Wednesday.
Phys.org / First electrically pumped perovskite polariton laser diode solves a decades-long challenge
Resolving a long-standing problem in semiconductor physics and optoelectronics, a team of researchers from Skoltech—a VEB.RF group institution—and their colleagues from ITMO University and HSE University have for the first ...
Phys.org / Lake ice loss could accelerate after winter temperatures cross critical thresholds
For lakes across the Northern Hemisphere, winter ice is more than a frozen surface. It is a seasonal regulator that shapes underwater ecosystems and energy balance. But as the planet warms, this frozen season is disappearing ...
Phys.org / Extragalactic positron-annihilation hotspots might mean Milky Way produces far more positrons than thought
Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...
Medical Xpress / Antihistamines likely offer no meaningful benefit for eczema and may increase harms
Adding oral antihistamines to existing eczema treatments is unlikely to lead to clinically important reductions in eczema and itch severity and may not reduce sleep disturbance or flare-ups, finds a review of the latest trial ...
Phys.org / Tabby's star may be orbited by a planetary-mass companion
By analyzing data from NASA's Transiting Exoplanet Survey Satellite (TESS) and conducting new radial velocity measurements, U.K. and French astronomers have found evidence that the mysterious Tabby's star may be orbited by ...
Medical Xpress / Chemicals present in drinking water may carry a hidden risk tied to uterine cancer
In a recent study, researchers examined whether certain chemicals present in public drinking water are linked to uterine cancer, the most common gynecological cancer in the United States and one that has been steadily increasing ...
Phys.org / Gonorrhea's own enzyme triggers therapy against multidrug-resistant strains in lab tests
Scientists at the Universities of Liverpool and Oxford have developed a promising new way to kill antibiotic-resistant strains of Neisseria gonorrhoeae, the bacterium that causes gonorrhea, using a targeted therapy that is ...
Tech Xplore / Stable-GFlowNet uncovers more hidden weaknesses in generative AI models
KAIST researchers have developed a safety verification technology that uncovers roughly seven times more hidden vulnerabilities in AI than existing methods. The technology is expected to serve as a foundation for developing ...
Phys.org / Moon's thick crust could amplify elusive gravitational-wave signals
Gravitational waves are tiny ripples in the fabric of spacetime that are produced when massive objects in the cosmos accelerate or collide. By detecting these waves, astrophysicists can study various cosmic events, including ...
Phys.org / What sheep's teeth can tell us about life in a medieval Kazakhstan town
You might not often think about the molars of livestock, but everything from the grass they eat to the water they drink can tell a story about how people lived centuries ago. An international collaboration led by University ...
